unable to select prompts on a epbcs report grid for graph

Summary:

Hi All, I am currently trying to create a report in epbcs reports module for a graph. I have many grids on the report and I need to show a graph for a certain account for the past six months based on the user prompt selection on the main grid. Requirement is that if user runs a report for Dec23 graph should display data from dec23 to July23. When i try to select currentPOV with the prompt, report module throws the error that prompts cannot be used in conjunction with currentPOV. Please let me know if any one has encountered
